Description

本発明は無線通信装置に関する。 The present invention relates to a wireless communications apparatus.

近年、携帯電話機やPCに代表される電子機器は、Bluetooth(登録商標)、無線LA Recently, electronic devices represented by mobile phones and the PC, Bluetooth (registered trademark), wireless LA
N、NFC(Near Field Communication)等、複数の無線通信機能を有するようになってきている。 N, NFC (Near Field Communication), etc., have come to have a plurality of wireless communication functions. このような電子機器において、例えばNFCのような近接無線通信方式を用いて、Bluetoothや無線LANのような近接無線通信方式よりも長い距離間で通信可能であって、比較的高速な通信が可能な通信方式の設定情報を交換して認証処理を実行し、データの送受信にはBluetoothや無線LANに通信を引き継ぐ技術(コネクションハンドオーバ:Connection Handover、以下ハンドオーバと称する)が提案されている(例えば、特許文献1、非特許文献1参照。)。 In such electronic devices, for example, by using the proximity wireless communication scheme such as NFC, a possible communication between a distance greater than the proximity wireless communication scheme such as Bluetooth or wireless LAN, and allows relatively high-speed communication run the exchange to the authentication process the setting information Do communication system, the transmission and reception of data takes over a communication to the Bluetooth or wireless LAN technology (connection handover: connection handover, hereinafter referred to as a handover) has been proposed (e.g., Patent Document 1, non-Patent reference 1.).

特開2008−160856号公報 JP 2008-160856 JP

非特許文献1に規定されているハンドオーバの仕様では、NFCを用いて別の高速な規格へ通信を引き継ぐハンドオーバの一方式として、Negotiated Handoverという方式が示されている。 The specification of handover as defined in Non-Patent Document 1, as a method for handover to take over the communication to another high-speed standards using NFC, scheme has been shown that Negotiated Handover. Negotiated Handoverでは、ハンドオーバを対向機器へ要求する端末(Requester)からハンドオーバ先の通信規格(Alternative Carrier)を1つ以上指定する。 In Negotiated Handover, it specifies the terminal (Requester) handover destination communication standard of (Alternative Carrier) 1 or more from the requesting handover to the counterpart apparatus. Requesterは、指定されたハンドオーバ先を示す情報と共に、そのハンドオーバ先の電源状態を対向機器(Selector)へ通知することができる。 Requester, together with information indicating the specified handover destination can be notified of the power state of the handover destination to the counter device (Selector). ハンドオーバ先の電源状態は、電源ONの状態(active)、電源ON処理中の状態(activating)、電源OFFの状態(inactive)、不明の状態(unknown)の4状態に分類され、これらのいずれかが指定されて対向機器へ通知される。 Handover target power state is the power ON state (active), state during power-ON process (activating), a state of power OFF (: inactive), are classified into four states unknown state (unknown unknown), one of these There is notified is specified to the opposite device. 一方、Requesterから要求を受けたSelectorは、Requesterから通知を受けた1つ以上のハンドオーバ先のうちの1つ以上を選択し、選択したハンドオーバ先を示す情報と共に、そのハンドオーバ先の電源状態をRequesterへ通知する。 Meanwhile, Selector having received the request from the Requester, select one or more of the one or more handover destination notified by the Requester, Requester together with information indicating a handover destination selected, the power state of the handover destination It is notified to.

図5は、NFCからBluetoothへハンドオーバするときの例である。 Figure 5 is an example in which a handover to the Bluetooth from NFC. NFCに対応する無線通信装置2台がNFCの通信可能な範囲内に近づけられて、NFC通信が確立した後に、RequesterからSelectorに対してハンドオーバ要求が送信される。 Two radio communication apparatus corresponding to the NFC is brought close to the communicable range of the NFC, after the NFC communication is established, the handover request is transmitted to the Selector from Requester. 図5の例では、ハンドオーバ要求には、ハンドオーバ先としてBluetoothが指定されてBluetoothの電源がONの状態であることが示され、ハンドオーバ要求に対してSelectorが送信する応答には、ハンドオーバ先としてBluetoothが選択されてBluetoothの電源がONの状態であることが示される。 In the example of FIG. 5, the handover request, is specified Bluetooth as the handover destination is shown that the power of Bluetooth is in the state ON, the the response Selector to the handover request is transmitted, Bluetooth as the handover destination There are selected by indicating that the power of Bluetooth is the state is ON. 更にこれらのハンドオーバ要求/応答を用いて、ハンドオーバ先として選択されたBluetoothアドレスやデバイスの種類、ペアリングに用いるハッシュやランダム値を通知することができるため、これらの情報を用いてRequesterとSelector間でのBluetoothのペアリングを行うことができる。 Further with these handover request / response, the selected Bluetooth address and device type as a handover destination, it is possible to notify the hash and random value used for pairing between the Requester and the Selector using the information Bluetooth pairing in can be carried out. そして、ペアリングが完了した後にBluetoothによるデータ通信が可能となる。 Then, data communication by Bluetooth is possible after the pairing is completed.

以上の例では、Requesterからハンドオーバ先としてBluetoothが指定されているとしたが、ハンドオーバ先としては、Bluetoothだけでなく無線LANを指定することも可能である。 In the above example, although the Bluetooth is specified as the handover destination from the Requester, as the handover destination, it is also possible to specify the wireless LAN as well as Bluetooth. つまり、ハンドオーバ要求によってSelectorに対して通知するハンドオーバ先の情報は、(Bluetooth)、(無線LAN)、(Bluetoothと無線LAN)の3通りの可能性がある。 In other words, the handover destination information to be notified to Selector by handover request, the possibility of three ways (Bluetooth), (wireless LAN), (Bluetooth and wireless LAN). このように、複数のハンドオーバ先が指定可能である場合に、特許文献1や非特許文献1では、Requester側でハンドオーバ先を指定するための判断する仕組みが無い。 Thus, when a plurality of handover destination can be specified, in Patent Document 1 and Non-Patent Document 1, there is no mechanism for determining for specifying a handover destination Requester side. そのため、Requesterがハンドオーバ可能な通信手段をSelectorへ通知し、それに対してSelectorの判断でハンドオーバ先を決定するというように、ハンドオーバ先の判断はSelectorに依存するという問題点がある。 Therefore, Requester notifies a handover possible communication means to the Selector, so that to determine a handover destination in contrast Selector decision, the handover destination determining there is a problem that depends on the Selector.

そこで本発明は、他端末へ現在接続している通信手段から通信を引き継ぐハンドオーバを要求するときに、ハンドオーバ先の通信手段を判断することができる無線通信装置を提供することを目的とする。 The present invention aims to provide a radio communication apparatus when requesting a handover to take over the communication from the communication means are currently connected to the other terminal, it is possible to determine the means of communication handover destination.

上記目的を達成するために、本発明による無線通信装置は、対向機器との通信を行う第1の通信手段と、前記第1の通信手段から通信を引き継ぐことが可能な複数の他の通信手段の電源状態を記憶する電源状態記憶手段と、前記第1の通信手段から前記複数の他の通信手段のいずれかに通信を引き継ぐ場合に、前記電源状態記憶手段によって記憶されている電源状態を確認し、電源状態がONである通信手段を通信の引継ぎ先として前記対向機器へ通信を引き継ぐための要求を送信する前記第1の通信手段によって送信するよう制御する制御手段とを有することを特徴としている。 To achieve the above object, a wireless communication apparatus according to the present invention, the first communication means and said first plurality of other communication means adapted to take over the communication from the communication means for communicating with other devices check power state storage means for storing a power state, when taking over the communication from the first communication means to one of said plurality of other communication means, a power supply state stored by said power supply state storage means and, as a feature that the power supply state and a control means for controlling so as to transmit by said first communication means for transmitting a request to take over the communication to the counter device communication means is ON as takeover destination of communication there.

本発明によれば、他端末へ現在接続している通信手段から通信を引き継ぐハンドオーバを要求するときに、ハンドオーバ先の通信手段を判断する無線通信装置を提供することができる。 According to the present invention, when requesting a handover to take over the communication from the communication means are currently connected to the other terminal, it is possible to provide a wireless communication device for determining the communication means of the handover destination.

以上のような構成を有する携帯電話機1が、Bluetoothの電源状態に応じたハンドオーバ要求を生成する場合の制御部10によって実行される処理について、図2のフローチャートを参照して説明する。 The portable telephone 1 having the above configuration, the processing executed by the control unit 10 when generating a handover request according to the power state of the Bluetooth, will be described with reference to the flowchart of FIG.

携帯電話機1は、NFC通信に対応している対向機器との距離が所定値以下に近づくと、携帯電話機1と対向機器間でのNFC通信を確立する(S11)。 Mobile phone 1, the distance between the opposed device that supports the NFC communication approaches a predetermined value or less, to establish the NFC communication between the cellular phone 1 and the counterpart apparatus (S11). NFC通信については、特開2008−160856号公報に記載されているため、詳細な説明を省略する。 The NFC communication, because it is described in JP 2008-160856, a detailed description thereof will be omitted.

対向機器とのNFC通信を確立した携帯電話機1は、電源情報取得手段11aによって、Bluetooth電源情報管理手段12bからBluetoothの電源状態を取得し(S12)、Bluetoothの電源がONの状態であるか否かを判定する(S13)。 Whether the mobile phone 1 that established the NFC communication with the counterpart apparatus is the power information acquisition unit 11a, acquires the power status of the Bluetooth from the Bluetooth power information management unit 12b (S12), the power of Bluetooth is in the state of ON It determines whether or not (S13). そして、Bluetoothの電源状態がONであれば(S13のYes)、ハンドオーバデータ生成手段11bによってBluetoothをハンドオーバ先としたハンドオーバ要求を生成して対向機器へ送信し(S14) Then, if ON the power state of the Bluetooth (S13 of Yes), the transmission by the handover data generating means 11b generates a handover request to Bluetooth and handover to the counterpart apparatus (S14)
、対向機器とのBluetooth接続を確立する(S17)。 To establish a Bluetooth connection with a counterpart apparatus (S17).

一方、電源情報取得手段11aがBluetooth電源情報管理手段12bから取得したBluetoothの電源状態がONの状態でない場合(S13のNo)、ハンドオーバ先の通信手段を選択させるためのユーザインタフェースを表示部50へ表示させる(S15)。 On the other hand, if the Bluetooth power when the power information acquisition unit 11a acquires from the Bluetooth power information managing unit 12b is not in a state of ON (the S13 No), the display unit 50 a user interface for selecting the means of communication handover destination It is displayed (S15). 図3は、ハンドオーバ先の通信手段を選択するために表示部50へ表示させるユーザインタフェースの例である。 Figure 3 is an example of a user interface to be displayed on the display unit 50 to select the communication means of the handover destination. 携帯電話機1の場合、ハンドオーバ先として選択可能な通信手段は、Bluetoothと無線LANであるため、この2つの通信手段の内いずれか一方を選択するためのユーザインタフェースを表示部50へ表示させ、操作部60によってユーザの選択操作を受け付ける。 In the mobile phone 1, selectable communication means as a handover destination are the Bluetooth and wireless LAN, and to display a user interface for selecting one of the two communication means to the display unit 50, an operation accepting user's selection operation by section 60. 操作部60によって受け付けられた選択操作は制御部10へ伝えられる。 Accepted by the operation unit 60 selects the operation is transmitted to the control unit 10. そして制御部10は、ハンドオーバデータ生成手段11bによって、ユーザに選択された通信手段をハンドオーバ先としたハンドオーバ要求を生成して対向機器へ送信し(S16)、ユーザに選択された通信手段による通信を確立する(S17)。 The control unit 10, the handover data generating unit 11b, and transmitted to the product to the counterpart device a handover request the handover destination communication means selected by the user (S16), the communication by the selected communication means to the user establishing (S17).

以上のような処理によれば、ハンドオーバ要求元の装置からハンドオーバ先の通信手段を判断することができ、Bluetoothの電源がONの状態であれば、ユーザの選択操作を受けることなくBluetoothをハンドオーバ先としたハンドオーバ要求を対向機器へ送信することができるため、ユーザの操作負担を軽減することができる。 According to the above process, it is possible to determine the means of communication the handover destination from the handover requesting unit, if the state of the power supply of the Bluetooth is ON, the handover destination Bluetooth without receiving a user's selection operation a handover request relative it is possible to transmit to the counterpart apparatus, it is possible to reduce the operation burden on the user.

図4は、Bluetoothの電源状態に応じてハンドオーバ先を決定する携帯電話機1においてBluetoothの電源がONの場合の処理を示したシーケンス図である。 Figure 4 is a sequence diagram Bluetooth power showed processing when the ON in the cellular phone 1 to determine the handover destination according to the power supply state of Bluetooth. 携帯電話機1が対向機器とNFC通信可能な範囲内に近接されると(S51)、NFC通信が確立する(S52)。 When the portable telephone 1 is close to the opposite device and the NFC within communication range (S51), NFC communication is established (S52). そして、Bluetoothの電源状態がONの状態であると(S53、S54)、Bluetoothをハンドオーバ先としたハンドオーバ要求を生成し(S55)、生成したハンドオーバ要求をNFC通信によって対向機器へ送信する(S56)。 Then, the Bluetooth power state is the state of ON (S53, S54), generates a handover request to Bluetooth and handover destination (S55), the generated handover request transmitted to the counterpart apparatus through the NFC communication (S56) . このハンドオーバ要求に対して、対向機器からBluetoothがONであることを示す応答を受けると(S57)、Bluetoothによって対向機器と接続する(S58)。 For this handover request receives a response indicating that Bluetooth is ON from the opposing device (S57), it is connected to the counter device by Bluetooth (S58). なお、ステップS57において、対向機器のBluetoothが利用できない状態である場合(Bluetoothの電源状態がinactiveであるとの通知を受けた場合)には、携帯電話機1側から対向機器に対してBluetoothの電源をON Incidentally, in step S57, the in the case of Bluetooth counterpart apparatus is in a state unavailable (if Bluetooth power state is notified that it is: inactive) is, Bluetooth power to the counter device from the portable telephone 1 side the ON
にするよう要求することも可能である。 It is also possible to request to. 図4のシーケンス図に表されるように、ユーザの操作はステップS51で携帯電話機を対向機器に近接させる動作だけであるため、ユーザにとって簡単な動作を行うだけでNFC通信からBluetoothへのハンドオーバを実現することができる。 As represented in the sequence diagram of FIG. 4, for the operation of the user it is only operation to close the cellular phone counterpart device in step S51, the handover just performing a simple operation for the user to Bluetooth from the NFC it can be realized.

例えば、自端末がある機器(例えばヘッドセット)とBluetoothによって接続している時に、このBluetooth接続を切断し、NFC通信可能な他の機器(例えばPC)とのBluetooth接続を確立しようとする場合、自端末のBluetoothの電源はONの状態である。 For example, if the equipment in the own terminal (for example, a headset) when connected by Bluetooth, disconnect the Bluetooth connection, trying to establish a Bluetooth connection with the NFC communication can be another device (e.g. PC), Bluetooth power of the terminal is the state is ON. そのため、他の機器とのBluetooth接続を確立するときに、ユーザからBluetoothをハンドオーバ先として指定する操作を受けなくても、他の機器とのNFC通信可能な距離まで自端末を近接させることによって、NFC通信が確立した後にBluetoothへのハンドオーバが実現する。 Therefore, when establishing a Bluetooth connection with another device, even without receiving the operation of designating a Bluetooth user as a handover destination, by close to its own terminal NFC to communicable distance with other devices, handover to Bluetooth after NFC communication has been established to achieve.

また例えば、自端末がNFC通信可能な対向機器とBluetoothによって接続している時に、何らかの原因でBluetooth接続が切断された場合、自端末のBluetoothの電源はONの状態である。 Further, for example, when the own terminal is connected by the NFC capable counterpart apparatus and Bluetooth, if the Bluetooth connection is broken for some reason, Bluetooth power of the terminal is the state is ON. そのため、この対向機器とNFC通信可能な距離まで自端末を近接させることによって、NFC通信が確立した後にBluetoothへのハンドオーバが実現する。 Therefore, by proximity to the terminal itself until the counter device and NFC communicable distance, to realize the handover to Bluetooth after NFC communication is established. このように、ユーザの指示操作無しにBluetooth切断後の再接続が可能となるので、すばやくBluetoothの再接続を行うことができる。 Thus, since it is possible to reconnect after Bluetooth cut instruction operation without the user can perform a quick Bluetooth reconnection.

なお、図2のフローチャートでは、Bluetoothの電源がONのときにBluetoothをハンドオーバ先としたハンドオーバ要求を対向機器へ送信する場合について説明したが、ステップS12とステップS13で電源状態を確認する通信手段は、Bluetoothに限定されることは無く、携帯電話機1が有する他の通信手段(例えば無線LAN)であっても良い。 In the flowchart of FIG. 2, a case has been described in which transmitting a handover request power Bluetooth is that the Bluetooth and the handover destination when the ON to the counter device, communication means for checking the power status in step S12 and step S13 , without to be limited to Bluetooth, it may be another communication means of the mobile phone 1 has (e.g., wireless LAN). 無線LANの電源状態を確認する場合、ステップS13で無線LANの電源がONの状態であるか否かを確認し、無線LANの電源がONの状態であれば、ステップS14で無線LANをハンドオーバ先としたハンドオーバ要求を対向機器へ送信し、ステップS17で無線LANによる通信を確立させる。 To check the power state of wireless LAN, a power supply of the wireless LAN is to verify whether the state of ON in step S13, if the state of the power supply of the wireless LAN is ON, the handover destination wireless LAN in step S14 It transmits to the handover request counter devices and, to establish communication by the wireless LAN in step S17.

また、図2のフローチャートでは、1つの通信手段(Bluetooth)の電源状態を確認するとして説明したが、複数の通信手段の電源状態を確認しても良い。 Further, in the flowchart of FIG. 2 it has been described as to check the power state of one communication means (Bluetooth), may check the power status of the plurality of communication means. 例えば、ステップS13でBluetoothの電源状態を確認し、Bluetoothの電源状態がONでない場合には無線LANの電源状態を確認しても良い。 For example, to check the power status of the Bluetooth in step S13, when the Bluetooth power state is not ON may check the power state of the wireless LAN. この場合、Bluetoothの電源状態がONではなく、無線LANの電源状態がONであるならば、無線LANをハンドオーバ先としたハンドオーバ要求を対向機器へ送信し、Bluetoothの電源状態がONではなく、無線LANの電源状態もONではないならば、ハンドオーバ先を選択させるためのユーザインタフェースを表示する。 In this case, rather than Bluetooth power state is ON, if the power status of the wireless LAN is ON, the sends a handover request to the wireless LAN as the handover destination to the opposite device, Bluetooth power state rather than ON, radio if LAN power states also are not ON, the displays a user interface for selecting a handover target.

また例えば、ステップS13でBluetoothの電源状態と無線LANの電源状態を確認し、どちらか一方の電源状態がONであるならば、電源状態がONである通信手段をハンドオーバ先として選択し、両方の電源状態がONである場合には、起動中のアプリケーションに応じていずれか一方の通信手段をハンドオーバ先として選択する場合も考えられる。 Further, for example, to check the power status of the Bluetooth power state and the wireless LAN in step S13, if either one of the power state is ON, and selects a communication unit power state is ON as a handover destination, both If the power state is oN, it is conceivable to select the one communication unit either in response to the running application as a handover destination.

起動中のアプリケーションに応じて通信手段を選択するためには、アプリケーションを識別する情報とそのアプリケーションを起動しているときに使用される可能性の高い通信手段を識別する情報とを対応付けて記憶部70へ予め記憶しておく。 To select a communication unit in accordance with the running application is stored in association with information identifying a high communication means could be used when running the information and its application identifying an application previously stored to the section 70. 例えば、音楽を再生するためのアプリケーションを使用している場合、再生する音楽をBluetoothを介してヘッドセットへ転送する可能性が高いと考えられる。 For example, if you have an application for playing the music, it is highly possible to be transferred to the headset through the Bluetooth music to be played. また、Webブラウザを起動しているときには無線LANのアクセスポイントとの無線LAN通信によってWebデータを受信する可能性が高いと考えられる。 Moreover, it is highly possible that receives Web data by the wireless LAN communication with an access point of the wireless LAN when running the Web browser. そこで、音楽再生のためのアプリケーションの識別情報とBluetoothであることを示す識別情報とを関連づけ、Webブラウザの識別情報と無線L Therefore, association with identification information indicating the identification information and Bluetooth application for music reproduction, the identification information of the Web browser and the wireless L
